[Calcified amorpheus tumour of the heart as the cause of near syncope].

Calcified amorphoeus tumour of the heart (cardiac CAT) is a rare non-neoplastic tumour of the heart. To the best of our knowledge, this is the first case report of cardiac CAT in Scandinavia. The patient was a 55-year-old woman with obesity, hypertension, hyperlipidaemia, a history of smoking, and a family history of ischaemic heart disease. She presented with dyspnoea and near syncope. The tumour was resected, and cytopathology was preformed on its content. Based on the cytopathology, the pathologist concluded that the tumour most likely was cardiac CAT, though a calcified myxoma could not be excluded with certainty.
